Sperm while on finasteride

I’m reading on the package of finasteride accord and it says that it lowers the sperm quality and that infertility is a possibility. Would I be risking going infertile if I were to take finasteride for 10 years?

Infertility would be a very remote possibility. I looked into this when one of my nephew’s sperm count dropped on finasteride. I found the decreased sperm counts is not uncommon when on finasteride. After that research, his wife became pregnant. I have had the opportunity to do sperm counts on some of my younger patients, a lower than average sperm counts have been seen.
